HQY-96 Plastic Ball Indentation Hardness Tester

HQY-96 Plastic Ball Indentation Hardness Tester

Product Name: Plastic Ball Indentation Hardness Tester

Product Model 2: HQY-96

3、 Overview:

The plastic ball indentation hardness tester refers to a device that measures the average pressure per unit indentation area of a steel ball of a specified diameter, which is vertically pressed onto the surface of a specimen under test load and held for a certain period of time.

The plastic ball indentation hardness tester developed by our company adopts automatic loading, timing selection, deformation acquisition and other methods, and eliminates the commonly used digital block display method, and adopts touch screen color display of Chinese characters and voice prompts. In this way, the operator can perform experimental operations based on the Chinese character prompts on the LCD screen after turning on, which greatly facilitates the user. The parameters of the plastic ball indentation hardness tester comply with the provisions of relevant standards such as GB3398.1-08 Plastic Hardness Determination Part 1 Ball Indentation Method, ISO 2039-1-2001 Plastic Hardness Determination Part 1 Ball Indentation Method, etc.

Characteristics of Plastic Ball Indentation Hardness Tester:

1. This instrument adopts microprocessor control and integrated, digital measurement and control technology. Set up the program according to the standard test procedure

2. Chinese color crystal display, touch screen operation, convenient and easy to understand.

3. Adopting digital micrometer, high-precision force measurement system, high measurement and control accuracy, and stable control.

4. Micro printers are used for data printing.

5. This instrument has been upgraded to touch screen control, which is innovative, easy to operate, and more user-friendly.

6. The original monochrome LCD display screen has been replaced with a large-sized 65535 true color screen, which provides better visual effects and displays more information on the interface.

7. Improved the calculation function of experimental results, retaining decimals and rounding the results to make the calculation more accurate.

8. Various parameter settings can be freely set, making it easier for testers to operate flexibly and meet more testing requirements.

9. Any step in the experiment can be manually skipped for easy testing.

4Plastic ball indentation hardness testerworking principle:

According to the relevant requirements of the standard, in a mechanism composed of a frame, loading device, indentation depth indicator device, timing device, and indenter (embedded with steel balls of specified diameter), the loading device vertically presses the indenter into the surface of the specimen under a given test load, and maintains the average pressure per unit indentation area for a certain period of time. Expressed in kgf/mm2 or N/mm2.

The hardness value of the ball indentation is calculated according to the following formula:

0．21P

H=------------------------

25πD（h-0.04）

In the formula: H - ball indentation hardness, kgf/mm2 or N/mm2

P - Test load, kgf or N;

D - diameter of steel ball, mm；

H - depth of indentation after correcting the deformation of the rack, mm。

Note: h=h1-h2;

H1- Depth of indentation under test load, mm；

H2- the deformation of the instrument rack under test load, mm
